On CAPS, 70% of the 791 members who have rated Zix believe the stock will outperform the S&P 500 going forward.

Just yesterday, one of those Fools, DCHomer13, succinctly summed up the Zix bull case for our community:

High renewal rate with customers. Email is becoming more frequent and at the same time people are starting to be more wary (NSA) of their Internet security. Zix Corp stands to capitalize on this combination through their secure email encryption software.    

If you want market-thumping returns, you need to put together the best portfolio you can. Of course, despite a perfect five-star rating, Zix may not be your top choice. Perhaps you're interested in major tech heavyweights.
